In most instances, stating categorically that an individual is malingering requires an explicit admission by that individual. Legally the term may be considered prejudicial and excluded on that basis. No current research exists regarding the frequency, behaviour or detection of successful malingerers. No neuropsychological inventories exist that can be used to conclusively determine if a patient is malingering, or to exclude a determination of malingering. Genuine neurological and psychiatric conditions may return false positives. Testing inventories cannot distinguish between exaggeration and fabrication. Psychological inventories rely on naivety. Criminally, an assessment may lead to punishment enhancement, and medically, to denial of future treatment. The DSM-V criteria faces scrutiny for providing poor guidelines. As such physicians ultimately rely on their intuition and gut feeling for any assessment, which is subject to prejudice and cognitive dissonance, and which has been shown to be unreliable in synthetic tests.

Malingering presumes an exhaustive diagnostic procedure has been performed. Exhaustive diagnostics are neither practical nor economically viable or judged to be in the best interests of the patient's health. Radiological and invasive exploratory procedures can be necessary for an accurate diagnosis yet pose a health risk to the patient. Radiographic diagnostics expose the patient to radiation and surgical diagnostic procedures can carry a high risk of complications and mortality, such as a lumbar puncture, the only reliable diagnostic procedure for diagnosing rare terminal forms of parasitization, which the CDC reports as only being diagnosed "post mortem" 75% of the time. A physician invariably faces limitations in the realms of resources, time and liability. Because an assessment, formal or informal, of malingering ceases the medical process, it may seem an attractive option for the physician and help them to cope with cognitive dissonance over their failure to effectively diagnose and treat a patient within constraints.

Patients with unresolved illness may be adversarial towards physicians, attempting to game the triage system in order to receive specialist care. Such cases fit the criteria for malingering, yet the patient is still in need of medical care.

For example, in a gatekeeper system, primary care physicians may restrict the availability of HIV testing to only patients who report high risk activity. A patient may then falsely report sexual and/or drug history and/or symptoms in order to elevate priority which can then go on to serve as diagnostically relevant history for an inaccurate path of further diagnosis.

Medical practitioners often believe that they can detect deception. In two studies, experienced medical practitioners including psychiatrists failed to perform better than chance when asked to detect lying and simulated patients. In 12 other studies, detection rates of simulated patients ranged between 0 and 25%. It's impossible to detect malingering from a clinical perspective.

Diagnosing factitious disorder imposed on self requires a clinical assessment. Clinicians should be aware that those presenting with symptoms (or persons reporting for that person) may malinger, and caution should be taken to ensure there is evidence for a diagnosis. Lab tests may be required, including complete blood count (CBC), urine toxicology, drug levels from blood, cultures, coagulation tests, assays for thyroid function, or DNA typing. In some cases CT scan, magnetic resonance imaging, psychological testing, electroencephalography, or electrocardiography may also be employed. A summary of more common and reported cases of factitious disorder (Munchausen syndrome), and the laboratory tests used to differentiate these from authentic disease is provided below:

There are several symptoms that together point to factitious disorder, including frequent hospitalizations, knowledge of several illnesses, frequently requesting medication such as pain killers, openness to extensive surgery, few or no visitors during hospitalizations, and exaggerated or fabricated stories about several medical problems. Factitious disorder should not be confused with hypochondria, as people with factitious disorder syndrome do not really believe they are sick; they only want to be sick, and thus fabricate the symptoms of an illness. It is also not the same as pretending to be sick for personal benefit such as being excused from work or school.

People may fake their symptoms in multiple ways. Other than making up past medical histories and faking illnesses, people might inflict harm on themselves by consuming laxatives or other substances, self-inflicting injury to induce bleeding, and altering laboratory samples.” Many of these conditions do not have clearly observable or diagnostic symptoms and sometimes the syndrome will go undetected because patients will fabricate identities when visiting the hospital several times. Factitious disorder has several complications, as these people will go to great lengths to fake their illness. Severe health problems, serious injuries, loss of limbs or organs, and even death are possible complications.

Because there is uncertainty in treating suspected factitious disorder imposed on self, some advocate that health care providers first explicitly rule out the possibility that the person has another early-stage disease. Then they may take a careful history and seek medical records to look for early deprivation, childhood abuse, or mental illness. If a person is at risk to themself, psychiatric hospitalization may be initiated.

Healthcare providers may consider working with mental health specialists to help treat the underlying mood or disorder as well as to avoid countertransference. Therapeutic and medical treatment may center on the underlying psychiatric disorder: a mood disorder, an anxiety disorder, or borderline personality disorder. The patient's prognosis depends upon the category under which the underlying disorder falls; depression and anxiety, for example, generally respond well to medication and/or cognitive behavioral therapy, whereas borderline personality disorder, like all personality disorders, is presumed to be pervasive and more stable over time, and thus offers a worse prognosis.

People affected may have multiple scars on their abdomen due to repeated "emergency" operations.

Munchausen syndrome by proxy is a controversial term. In the World Health Organization's International Statistical Classification of Diseases, 10th Revision (ICD-10), the official diagnosis is factitious disorder (301.51 in ICD-9, F68.12 in ICD-10). Within the United States, factitious disorder imposed on another (FDIA or FDIoA) was officially recognized as a disorder in 2013, while in the United Kingdom, it is known as fabricated or induced illness by carers (FII).

In DSM-5, the diagnostic manual published by the American Psychiatric Association in 2013, this disorder is listed under "301.51 Factitious disorder". This, in turn, encompasses two types:

- "Factitious disorder imposed on self" – (formerly Munchausen syndrome).

- "Factitious disorder imposed on another" – (formerly Munchausen syndrome by proxy); diagnosis assigned to the perpetrator; the victim may be assigned an abuse diagnosis (e.g. child abuse).

MSbP is rare. A recent systematic study in Italy found that in a series of over 700 patients admitted to a pediatric ward, 4 cases met the diagnostic criteria for MSbP (0.53%). In this study, stringent diagnostic criteria were used, which required at least one test outcome or event that could not possibly have occurred without deliberate intervention by the MSbP person.

One study showed that in 93 percent of MSbP cases, the abuser is the mother or another female guardian or caregiver. This may be attributed to the prevalent socialization pattern that places females in the primary care-taking role. Of course, it could also be a gender trait rooted in genetics, as it is easy to see how females who seek attention as victims could gain an evolutionary advantage, while men seeking the same would be unfavoured for physical protection and mating. A psychodynamic model of this kind of maternal abuse exists.

MSbP may be more prevalent in the parents of those with a learning difficulty or mental incapacity, and as such the apparent patient could, in fact, be an adult.

Fathers and other male caregivers have been the perpetrators in only 7% of the cases studied. When they are not actively involved in the abuse, the fathers or male guardians of MSbP victims are often described as being distant, emotionally disengaged, and powerless. These men play a passive role in MSbP by being frequently absent from the home and rarely visiting the hospitalized child. Usually, they vehemently deny the possibility of abuse, even in the face of overwhelming evidence or their child's pleas for help.

Overall, male and female children are equally likely to be the victim of MSbP. In the few cases where the father is the perpetrator, however, the victim is three times more likely to be male.

The word '' means 'substitute'. It is coded in the DSM-IV under Factitious Disorder NOS (not otherwise specified). Münchausen by proxy is the involuntary use of another individual to play the patient role. For example, false symptoms are produced in children by the caregivers or parents, to produce the appearance of illness, or they may give misleading medical histories about their children. The parent may falsify the child's medical history or tamper with laboratory tests to make the child appear sick. Occasionally, in Münchausen by proxy, the caregiver actually injures the child or makes it sick to ensure that the child is treated. For instance, a father whose son is coeliac might knowingly introduce gluten into the diet. Such parents may be validated by the attention that they receive from having a sick child.

The evaluative context (medical-legal and forensic) exerts distorting impact on the tendency of subjects to amplify or not the self-reported symptoms. This distorting effect is present also when subjects are truly suffering from mental pathology.

No true psychiatric medications are prescribed for factitious disorder. However, selective serotonin reuptake inhibitors (SSRIs) can help manage underlying problems. Medicines such as SSRIs that are used to treat mood disorders can be used to treat FD, as a mood disorder may be the underlying cause of FD. Some authors (such as Prior and Gordon 1997) also report good responses to antipsychotic drugs such as Pimozide. Family therapy can also help. In such therapy, families are helped to better understand patients (the individual in the family with FD) and that person's need for attention.

In this therapeutic setting, the family is urged not to condone or reward the FD individual's behavior. This form of treatment can be unsuccessful if the family is uncooperative or displays signs of denial and/or antisocial disorder. Psychotherapy is another method used to treat the disorder. These sessions should focus on the psychiatrist's establishing and maintaining a relationship with the patient. Such a relationship may help to contain symptoms of FD. Monitoring is also a form that may be indicated for the FD patient's own good; FD (especially proxy) can be detrimental to an individual's health—if they are, in fact, causing true physiological illnesses. Even faked illnesses/injuries can be dangerous, and might be monitored for fear that unnecessary surgery may subsequently be performed.

Psychiatrists seek to provide a medical diagnosis of individuals by an assessment of symptoms, signs and impairment associated with particular types of mental disorder. Other mental health professionals, such as clinical psychologists, may or may not apply the same diagnostic categories to their clinical formulation of a client's difficulties and circumstances. The majority of mental health problems are, at least initially, assessed and treated by family physicians (in the UK general practitioners) during consultations, who may refer a patient on for more specialist diagnosis in acute or chronic cases.

Routine diagnostic practice in mental health services typically involves an interview known as a mental status examination, where evaluations are made of appearance and behavior, self-reported symptoms, mental health history, and current life circumstances. The views of other professionals, relatives or other third parties may be taken into account. A physical examination to check for ill health or the effects of medications or other drugs may be conducted. Psychological testing is sometimes used via paper-and-pen or computerized questionnaires, which may include algorithms based on ticking off standardized diagnostic criteria, and in rare specialist cases neuroimaging tests may be requested, but such methods are more commonly found in research studies than routine clinical practice.

Time and budgetary constraints often limit practicing psychiatrists from conducting more thorough diagnostic evaluations. It has been found that most clinicians evaluate patients using an unstructured, open-ended approach, with limited training in evidence-based assessment methods, and that inaccurate diagnosis may be common in routine practice. In addition, comorbidity is very common in psychiatric diagnosis, where the same person meets the criteria for more than one disorder. On the other hand, a person may have several different difficulties only some of which meet the criteria for being diagnosed. There may be specific problems with accurate diagnosis in developing countries.

More structured approaches are being increasingly used to measure levels of mental illness.

- HoNOS is the most widely used measure in English mental health services, being used by at least 61 trusts. In HoNOS a score of 0–4 is given for each of 12 factors, based on functional living capacity. Research has been supportive of HoNOS, although some questions have been asked about whether it provides adequate coverage of the range and complexity of mental illness problems, and whether the fact that often only 3 of the 12 scales vary over time gives enough subtlety to accurately measure outcomes of treatment.

During a period of 13 years (1980–1993) for which admissions to the Kfar Shaul Mental Health Centre in Jerusalem were analysed, it was reported that 1,200 tourists with severe, Jerusalem-themed mental problems were referred to this clinic. Of these, 470 were admitted to hospital. On average, 100 such tourists have been seen annually, 40 of them requiring admission to hospital. About three and a half million tourists visit Jerusalem each year. Kalian and Witztum note that as a proportion of the total numbers of tourists visiting the city, this is not significantly different from any other city.

Since the 1980s, Paula Caplan has been concerned about the subjectivity of psychiatric diagnosis, and people being arbitrarily “slapped with a psychiatric label.” Caplan says because psychiatric diagnosis is unregulated, doctors are not required to spend much time interviewing patients or to seek a second opinion. The Diagnostic and Statistical Manual of Mental Disorders can lead a psychiatrist to focus on narrow checklists of symptoms, with little consideration of what is actually causing the patient’s problems. So, according to Caplan, getting a psychiatric diagnosis and label often stands in the way of recovery.

In 2013, psychiatrist Allen Frances wrote a paper entitled "The New Crisis of Confidence in Psychiatric Diagnosis", which said that "psychiatric diagnosis… still relies exclusively on fallible subjective judgments rather than objective biological tests." Frances was also concerned about "unpredictable overdiagnosis." For many years, marginalized psychiatrists (such as Peter Breggin, Thomas Szasz) and outside critics (such as Stuart A. Kirk) have "been accusing psychiatry of engaging in the systematic medicalization of normality." More recently these concerns have come from insiders who have worked for and promoted the American Psychiatric Association (e.g., Robert Spitzer, Allen Frances). A 2002 editorial in the "British Medical Journal" warned of inappropriate medicalization leading to disease mongering, where the boundaries of the definition of illnesses are expanded to include personal problems as medical problems or risks of diseases are emphasized to broaden the market for medications.

Munchausen by Internet is a pattern of behavior akin to Munchausen syndrome (renamed factitious disorder imposed on self), a psychiatric disorder, wherein those affected feign disease, illness, or psychological trauma to draw attention, sympathy, or reassurance to themselves. In Munchausen by internet, users seek attention by feigning illnesses in online venues such as chat rooms, message boards, and Internet Relay Chat (IRC). It has been described in medical literature as a manifestation of factitious disorder imposed on self, or if claiming illness of a child or other family member, factitious disorder imposed on another. Reports of users who deceive Internet forum participants by portraying themselves as gravely ill or as victims of violence first appeared in the 1990s due to the relative newness of Internet communications. The pattern was identified in 1998 by psychiatrist Marc Feldman, who created the term "Münchausen by Internet" in 2000. It is not included in the fifth revision of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-5).

The development of factitious disorders in online venues is made easier by the availability of medical literature on the Internet, the anonymous and malleable nature of online identities, and the existence of communication forums established for the sole purpose of giving support to members facing significant health or psychological problems. Several high-profile cases have demonstrated behavior patterns which are common among those who pose as gravely ill or as victims of violence, or whose deaths are announced to online forums. The virtual communities that were created to give support, as well as general non-medical communities, often express genuine sympathy and grief for the purported victims. When fabrications are suspected or confirmed, the ensuing discussion can create schisms in online communities, destroying some and altering the trusting nature of individual members in others.

The term "Munchausen by Internet" was first used in an article published in the "Southern Medical Journal" written by Marc Feldman in 2000. Feldman, a clinical professor of psychiatry at the University of Alabama at Birmingham, gave a name to the phenomenon in 2000, but he co-authored an article on the topic two years earlier in the "Western Journal of Medicine", using the description "virtual factitious disorder". Factitious disorders are described in the "Diagnostic and Statistical Manual of Mental Disorders: DSM-IV-TR" (DSM) as psychological disorders involving the production of non-existent physical or psychological ailments to earn sympathy. These illnesses are feigned not for monetary gain or to avoid inconvenient situations, but to attract compassion or to control others. Chronic manifestation of factitious disorder is often called Munchausen syndrome, after a book about the exaggerated accounts of the adventures of Baron Munchausen, a German cavalry officer in the Russian Army, that was written by Rudolf Erich Raspe. When the symptoms of another person, such as a child or an elderly parent, are purposely induced by the caregiver, it is called factitious disorder imposed on another, or Munchausen syndrome by proxy.

Feldman noted that the advent of online support groups, combined with access to vast stores of medical information, enabled individuals seeking to gain sympathy by relating a series of harrowing medical or psychological problems that defy comprehension to misuse the groups. Communication forums specializing in medical or psychological recovery were established to give lay users support in navigating often confusing and frustrating medical processes and bureaucracy. Communities often formed on those forums, with the goal of sharing information to help other members. Medical websites also became common, giving lay users access to literature in a way that was accessible to those without specific medical training. As Internet communication grew in popularity, users began to forgo the doctors and hospitals often consulted for medical advice. Frequenting virtual communities that have experience with a medical problem, Feldman notes, is easier than going through the physical pain or illness that would be necessary before visiting a doctor to get the attention sought. By pretending to be gravely ill, Internet users can gain sympathy from a group whose sole reason for existence is support. Health care professionals, with their limited time, greater medical knowledge, and tendency to be more skeptical in their diagnoses, may be less likely to provide that support.

"Jerusalem syndrome as a discrete form, uncompounded by previous mental illness." This describes the best-known type, whereby a previously mentally balanced person becomes psychotic after arriving in Jerusalem. The psychosis is characterised by an intense religious character and typically resolves to full recovery after a few weeks or after being removed from the locality. It shares some features with the diagnostic category of a "brief psychotic episode", although a distinct pattern of behaviors has been noted:

1. Anxiety, agitation, nervousness and tension, plus other unspecified reactions.

2. Declaration of the desire to split away from the group or the family and to tour Jerusalem alone. Tour guides aware of the Jerusalem syndrome and of the significance of such declarations may at this point refer the tourist to an institution for psychiatric evaluation in an attempt to preempt the subsequent stages of the syndrome. If unattended, these stages are usually unavoidable.

3. A need to be clean and pure: obsession with taking baths and showers; compulsive fingernail and toenail cutting.

4. Preparation, often with the aid of hotel bed-linen, of a long, ankle-length, toga-like gown, which is always white.

5. The need to shout psalms or verses from the Bible, or to sing hymns or spirituals loudly. Manifestations of this type serve as a warning to hotel personnel and tourist guides, who should then attempt to have the tourist taken for professional treatment. Failing this, the two last stages will develop.

6. A procession or march to one of Jerusalem's holy places, ex:The Western Wall.

7. Delivery of a sermon in a holy place. The sermon is typically based on a plea to humankind to adopt a more wholesome, moral, simple way of life. Such sermons are typically ill-prepared and disjointed.

8. Paranoid belief that a Jerusalem syndrome agency is after the individual, causing their symptoms of psychosis through poisoning and medicating.

Bar-El et al. reported 42 such cases over a period of 13 years, but in no case were they able to actually confirm that the condition was temporary.

Although medication is the first-line treatment for most psychiatric disorders, it does not always improve every aspect of a patient's life, and for the negative symptoms in schizophrenia, the responses to anti-psychotics are less favourable than for positive symptoms. As a result, psychotherapy might be an alternative for the treatment of these symptoms, even if medication has a good effect on other manifestations of the disorder.

Cognitive behavioural therapy (CBT), is the kind of psychotherapy that shows most promise in treating avolition (and other negative symptoms of schizophrenia), but more research is needed in the area. CBT focuses on understanding how thoughts and feelings influence behaviour, in order to help individuals develop methods and strategies to better handle the implications of their disorder. Some research suggests that CBT focusing on social skills and practice of interpersonal situations, like job interviews, seeing a doctor (to discuss medication, for example), or interacting with friends and co-workers, as well as seemingly simple things like riding a bus, might reduce negative symptoms of schizophrenia and be beneficial to patients with avolition.

Other forms of psychotherapy might also complement the role of medication and help patients, their families, and friends to work through emotional and other challenges of living with a chronic psychological disorder, including avolition.

A monothematic delusion is a delusional state that concerns only one particular topic. This is contrasted by what is sometimes called "multi-thematic" or "polythematic" delusions where the person has a range of delusions (typically the case of schizophrenia). These disorders can occur within the context of schizophrenia or dementia or they can occur without any other signs of mental illness. When these disorders are found outside the context of mental illness, they are often caused by organic dysfunction as a result of traumatic brain injury, stroke, or neurological illness.

People who experience these delusions as a result of organic dysfunction often do not have any obvious intellectual deficiency nor do they have any other symptoms. Additionally, a few of these people even have some awareness that their beliefs are bizarre, yet they cannot be persuaded that their beliefs are false.

The mental health community does not recognize work aversion as an illness or disease and therefore no medically recognized treatments exist. Those attempting to treat work aversion as an illness may use psychotherapy, counseling, medication, or some more unusual forms of treatment.

In the case where the person has not worked for a while due to a workplace injury, work-hardening can be used to build strength. The person works for a brief period of time in the first week, such as two hours per day and increases the amount of work each week until full-time hours are reached.

Timothy F. Jones, of the Tennessee Department of Health, recommends the following action be taken in the case of an outbreak:

- Attempt to separate persons with illness associated with the outbreak.

- Promptly perform physical examination and basic laboratory testing sufficient to exclude serious acute illness.

- Monitor and provide oxygen as necessary for hyperventilation.

- Minimize unnecessary exposure to medical procedures, emergency personnel, media or other potential anxiety-stimulating situations.

- Notify public health authorities of apparent outbreak.

- Openly communicate with physicians caring for other patients.

- Promptly communicate results of laboratory and environmental testing to patients.

- While maintaining confidentiality, explain that other people are experiencing similar symptoms and improving without complications.

- Remind patients that rumors and reports of "suspected causes" are not equivalent to confirmed results.

- Acknowledge that symptoms experienced by the patient are real.

- Explain potential contribution of anxiety to the patient's symptoms.

- Reassure patient that long-term sequelae from current illness are not expected.

- As appropriate, reassure patient that thorough clinical, epidemiologic and environmental investigations have identified no toxic cause for the outbreak or reason for further concern.

Some responses by authorities to MPI are not appropriate. Intense media coverage seems to exacerbate outbreaks. Once it is determined that the illness is psychogenic, it should not be given credence by authorities. For example, in the Singapore factory case study, calling in a medicine man to perform an exorcism seemed to perpetuate the outbreak.

The delusions that fall under this category are:

- Capgras delusion: the belief that (usually) a close relative or spouse has been replaced by an identical-looking impostor.

- Fregoli delusion: the belief that various people whom the believer meets are actually the same person in disguise.

- Intermetamorphosis: the belief that people in one's environment swap identities with each other while maintaining the same appearance.

- Subjective doubles: a person believes there is a doppelgänger or double of him- or herself carrying out independent actions.

- Cotard delusion: the belief that oneself is dead or does not exist; sometimes coupled with the belief that one is putrefying or missing internal organs.

- Mirrored-self misidentification: the belief that one's reflection in a mirror is some other person.

- Reduplicative paramnesia: the belief that a familiar person, place, object, or body part has been duplicated. For example, a person may believe that they are, in fact, not in the hospital to which they were admitted, but in an identical-looking hospital in a different part of the country.

- Somatoparaphrenia: the delusion where one denies ownership of a limb or an entire side of one's body (often connected with stroke).

Note that some of these delusions are sometimes grouped under the umbrella term of delusional misidentification syndrome.

The hypothesis that those prone to extroversion or neuroticism, or those with low IQ scores, are more likely to be affected in an outbreak of hysterical epidemic has not been consistently supported by research. Bartholomew and Wesseley state that it “seems clear that there is no particular predisposition to mass sociogenic illness and it is a behavioural reaction that anyone can show in the right circumstances.”

Females are affected with mass psychogenic illness at greater rates than males. Adolescents and children are frequently affected in cases of MPI.

Diplomatic illness is the practice amongst diplomats and government ministers of feigning illness, or another debilitating condition, to avoid engaging in diplomatic or social engagements. The excuse of ill-health is designed to avoid formally offending the host or other parties. The term also refers to the period during which the "diplomatic illness" is claimed to persist.

The diagnosis of pseudoneurotic schizophrenia can only be made with clinical observation by a mental health professional and by the patient's explanation of his or her experiences. A patient must identify with at least two of these symptoms in order to be distinguished as a pseudoneurotic schizophrenic. The intensity of a symptom may vary with the individual patient's severity of the disorder. The symptoms are organized into disorders of thinking and association, disorders of emotional regulation, disorders of sensorimotor and autonomic functioning, pan-anxiety, pan-neurosis, and pansexuality. The two symptoms can fall under any of these categories.

Pseudoneurotic schizophrenia is a postulated mental disorder categorized by the presence of two or more symptoms of mental illness such as anxiety, hysteria, and phobic or obsessive-compulsive neuroses. It is often acknowledged as a personality disorder. Patients generally display salient anxiety symptoms that disguise an underlying psychotic disorder.

In the 1940s, psychiatrists Paul Hoch and Philip Polatin created the term pseudoneurotic schizophrenia. This mental illness, however, is no longer acknowledged as a clinical entity. In 1972 it went on to be called borderline personality disorder, a term coined by Otto Friedmann Kernberg, which referred to an expansive range of issues.

Pseudoneurotic schizophrenia is in the Russian adapted version of the ICD-10 (code F21.3).

Implications from avolition often result in social deficits. Not being able to initiate and perform purposeful activities can have many implications for a person with avolition. By disrupting interactions with both familiar and unfamiliar people, it jeopardizes the patient's social relations. When part of a severe mental illness, avolition has been reported, in first person accounts, to lead to physical and mental inability to both initiate and maintain relationships, as well as work, eat, drink or even sleep.

Clinically, it may be difficult to engage an individual experiencing avolition in active participation of psychotherapy. Patients are also faced with the stresses of coping with and accepting a mental illness and the stigma that often accompanies such a diagnosis and its symptoms. Regarding schizophrenia, the American Psychiatric Association reported in 2013 that there currently are "no treatments with proven efficacy for primary negative symptoms" (such as avolition). Together with schizophrenia's chronic nature, such facts added to the outlook of never getting well, might further implicate feelings of hopelessness and similar in patients as well as their friends and family.

Work aversion usually occurs in persons who have previously been employed, and can have a variety of causes. These include:

- Boredom with work: Holding a boring job early in life can lead to the impression later that all work is boring.
